' CLOSUBE.

Application led September 13, 1926. Serial No. 135,047.

My invention relates to closures, and the principal object of my invention is to provide an improved closure capable of replacing closures of the type now in use. In

the drawings accompanying this specification and forming a part of this application I have shown, for purposes of illustration, one embodiment which my invention may assume. In these drawings:

Figure 1 is a side elevation of this illustrative embodiment of my invention.

Figure 2 is a bottom View of this illustrative embodiment of my invention,

Figure 3 is a section on the line 3 3 of Figure 2,

' Figure 4 is a section on the line 4 4 of Figure 2,

Figure 5 is a plan view lof an'alternative form of disc whlch I may employ with this embodiment of my invention,

Figure 6 is a view similar to Figure 3 showing a third form of disc which I may employ with this embodiment of myiinvention,

Figure 7 is a view similar to Figure 5 showing this third form of disc, while Figures 8 and. 9` are views similar to Figures 2 and 3 showing an alternative method of-securing the parts assembled.

The embodiment of my invention as shown in Figures' 1 through 4 comprises: a cap member 11 having a top section 12 consisting of an outer annular portion 13, an inner annular portion 14 lying in a plane parallel to but slightly above the plane of the outer annular Iportion 13, an annular uniting portion 15 interposed between the outer annular portion 13 and the inner annular portion 14 uniting the inner periphery of the outer annular portion 13 with the outer peri hery of the inner annular portion 14, an a generally spherical upwardly convexed portion 16 closing the opening within the inner annular portion 14 and provided centrally with a vent 17 ,A and havlng also a skirt section 18 formed in a single piece with the top section 12, and depending from the outer periphery of the outer annular ortion 13 of the top section 12; and a locking member 19 comprising a depressed central section 20, a air of arm sections 2l extending outward y from the depressed central section` 20 into position tol engage with cooperating lookin means of the'bayonet joint type carriedy y the tube with which the-closure is to be employed, and securing` sections 22peX-tending from the centrally depressed section -20 intermediate the arm sections 21 upwardly as portions 23 generally perpendicular to the centrally depressed section 20, and then outwardly as portions 24 generally parallel to the central depressed section 20, and to the inner annular portion 14 of the top section 12 of the cap member 11, substantially into engagement with the shoulder formed by the annular uniting portion 15 of the top section 12 of the cap member 11; and an intermediate disc member 25v interposed between the outwardly extending portions 24 of the securing sections 22 of the locking member 19 and the inner annular portion 14 of the top section 12 of the cap member 11, and provided with a vent 26 substantially in alignment with the vent 17 in the spherical portion 16 of the top section 12 ofthe cap member 11; and securing means securing the locking member 19 to the cap member 11 with theintermediate disc member 25 -assembled in position therebetween, herein shown as rivets 27 extending through the outwardly extending portions of the securing sections 22 of the looking member 19, and through the intermediate.dise member 25, and through the inner annular portion 14 of the top section 12 of the cap member 11.

Under certain circumstances I may prefer to dispose the vents in the cap member and yin the intermediate disc member out of alignment, and in such case I may use the intermediate disc member 28 disclosed in Figure 5 and provided with a plurality of vents 29 disposed removed from the center of the disc member 28 and herein shown as three in number arranged in a circle concentric with the center of the disc member 28.

Under other circumstances I may prefer to insure that any fluid finding its Way into the space between the intermediate disc member and the top section of the cap member drains readily through the vent in the intermediate disc member, and in that case I may prefer' to use lthefintermediate disc member 30 shown in Figures 6 and 7 and comprising a flat annular outer section 31 105 and a downwardly convexed central section 32 pierced centrally by a vent 33.

And under some circumstances I may desire to eliminate the rivets 27 projecting through the upper surface of the top section of the cap member, and in that case 1 may employ the construction shown in Figures 8 and 9v wherein 1 have shown a cap member 34 andan intermediate disc member 35 and a locking member 36 secured together by a plurality of welds 37 extending from the locking member 36 through the intermediate disc member 35 to the cap mem-` ber 311.

lit will of course be understood that 1 may use this weld connection with any one of the three forms of intermediate disc member shown herein.

1t will also be. understood that in the event li employ a libre intermediate disc member I may still use this weld connection by terminating the intermediate disc inember inwardly of the inner annular portion of the top section of the cap member so that the intermediate disc member is no longer interposed directly between the cap member and the locking member.

1t will also be understood that l may employ this same dise member consti-notion when the parts are riveted together,` and when the. disc member is ot metal.

In any case, however, 1 `prefer to employ with, my closure an annular washer member 38 interposed between the top of the tube and vthe bottom face of the outer annular portion of the top section of the cap member, and in order to adord this washer member a secure bearing against the cap member I prefer to at all times form the outer annular ortion of the top section of the cap mem er extending inwardly over the top of the tube to be closed.

And I also `prefer to strengthen and stiften the arm sections 21, and the connection of the arm sections 21 to the depressed central section 20, by ribs 39 pressed outwardly from the arm sections 21 and depressed central section 20, as shown.

From the above disclosure it' will be obvious to those skilled in the art that lt have provided a closure accomplishing at least the principal object of my invention. At the same time it will also be obvious to those skilled inthe art that the'particular embodiment of my invention herein shown and described possesses advantages other than those speci cally pointed out, and also that this particular embodiment of my yin'- vention herein shown may be variously changed and modified without departing from the spirit of my invention or sacrilicing the advantages thereof. lit will therefore be understood that the disclosure herein is illustrative only, and that Imy invention is not limited thereto.
